Adult sex ratio (ASR) exhibits immense variation in nature, although neither the causes nor
the implications of this variation are fully understood. According to theory, the ASR is …

Intraspecific food competition exerts powerful selective forces on all animals; successful
foragers thrive relative to weaker conspecifics. Understanding competition is therefore …

This book celebrates the guppy's unique contribution to evolutionary ecology. Ever since
Caryl Haskins described guppy populations as a'natural experiment'because of the way …

The social fine structure of a population plays a central role in ecological and evolutionary
processes. Whilst many studies have investigated how morphological traits such as size …

Social network theory is used to elicit details of the social structure of a population of free–
ranging guppies, Poecilia reticulata. They were found to have a complex and highly …

The mechanisms underpinning the structure of social networks in multiple fish populations
were investigated. To our knowledge this is the first study to provide replication of social …

Alien species often flourish and become invasive in urban ecosystems. How and why
invaders succeed in urban systems is an important, yet poorly understood, question. We …

Understanding how individuals modify their social interactions in response to infectious
disease is of central importance for our comprehension of how disease dynamics operate in …

The composition of an animal group can impact greatly on the survival and success of its
individual members. Much recent work has concentrated on behavioral variation within …

In contrast to the substantial number of theoretical papers that have examined the
mechanisms by which cooperation may evolve, very few studies have investigated patterns …
